AUTOMOBILE-TIRE.

Application filed October 4, 1969. Serial No. 520,798.

, to which it appertains to niale and use the saine.

This invention relates to automobile tires ot the cushion type.

The object ot the invention is to provide a tire ot this character which shall loc siniple in construction, efficient and durable in use, and in which the minimum ot' resiliency shall bc retained et all tiines with a. inoxiuuuu danger ot derangenient in use.

lliith the -above and other objects in View which will later appear as the nature ot the invention is better umilerstood, the seine consists in the novel construction sind coinloi'ne tion ot parts as will be hereinafter tully described and claimed.

ln describing the invention in erence vill. be had drawings forming porto this specification, wherein lilte characters ot reference denote correspoinling parts in the several views;

and in whichfd T ure l a view in side elevation, 'partly a rruginent o' an automobile -d with the improvements ot invention; lfie. 9., a transverse secti n on 'the line 2*2 ot Fig. l, looking` in the i, ection indicated by the arrows; Fig. oionzil view on the lino wheel 1 .i the present il. n transverse "#3 Fig. l, looking in the direction indicated by tie arrows; yFig. l? a detail view ot a fragment ot the housing;l shield oli the tire, showing the piste winch connects the adya cent ends ot the housing shield; end. Fig. 5,

a sectional 'view ot the housing shield on the line 5*-5 ot l. looking in the direction indicated by the arro\-vs.`

Referring to the drawings, l designates the telly olf the Wheel :and 2 the inner rim7 which is of metal, and fl thne outer riin which is also ot metal. in order to retain the tivo rims in proper spaced relation to each other and also to insure the required resiliency, a series ot levers t employed, of which there may be any niunl'ier, the Whif.:h is piveted to tl ne outer rim :it 5. The

detail re. to the eccoinpanying4 outer end of each oi".

inner end of each lever is turned at an angle to its longitudinal axis to provide an arm G which bears squarely upon the inner rim '2, and cariied by this extension is a stud 7 that is designed lo project into the inner end ot a coil spring` S, the outer end of which spring is engaged by a pin 9 carried by the outer rnn As shown in Figs. 2, and 15 the outer riin 3 is approximately Ushaped in cross section, :ind is ot considerably less width than the inner rim 2. the latter being of greater width than the telly. The inner riin 2 is provided with flanges l() that are laterally channeled as at ll for the purpose ol receiving` a pack ingol l2 to coact with :i shield lf3 to preclude the entrance ot dust to the interior ot' the tire. l

ln order to cause the shield 13 to move positively with the rini, tivo curved levers lil are einployed. Said levers are arranged respectively on cach side ot the longitudinal axis oli the wheel and pivoted at l5 and 16 to the riins 2 and il, as clearly shown in Fig. 3.

The shield lo which reference has been made is a trvo-psrt structure and entirely houses the two rin'is, and a portion ot the telly. and the parts ot seid shield are ssseinbled by plates l? which over-lap the adjacentends ot each part ot the shield end are secured thereto by bolts or otherwise. lt will ot course be understood that said plates l'i'" correspond in tbrniation to the crossseetionnl contour of the shield and are disposed on opposite es thereot and terminate short og the tread portion ot the shield. lt is designed that the shield 13 shall bear closely n l riui, thus to re tain the iucling in place, sind proper working ot the levers and thus innintnin the resiliency ot the tire throughout prolonged use. lhere is an oil tube 18 coinbined with the telly which enters the chemn her detined by the shield and has a closure or cap 19. llhen oil has once been supplied to the in terior ot the tire it Will reinain there almost indelinitely so that spring and the-easy working' ot the series ot levers upon their pivots while rust ot the parts which w breakage is prevented.

A series of U-s'liaped braces l designed to prevent the sprew'ling oli the shield '13 are disposed around the under onld lead to CIl fainst the flanges l() ,of the inner also exclude dust or sand, in order to insure l the action of the will be assured,

side ot the -telly wheel.

I, To render the tire non-sklddlng as far as is possible the tread portion ofthe shield is provided with closely assembled studs or projections 20 which may be either integral with the shield or secured thereto in any preferred manner- It will be seen from theforegoing description, that although the improvements herein described are simple in character they will be thoroughly effective for the purposes designed and will coaet in the production of a rim, a plurality of ftweenu'd rim's,

durable and practical form of automobile tire.

What is claimed is:

In a cushion tire, an inner rim, an outer bent levers disposed beone 4arm of each lever being pivo'ially connected to the outer rim and the hend of each lever resting on theinner rim toA form a fulcrum, and a plurality of l springs each interposed between the remain- -mg arm of each lever and the outer rim.

In ltestimony whereof, I aix my signature, 1n presence of two witnesses.
